They were locked in a duel.

Orange and blue fire clashed, the embers smoldering the ground around their feet.

Golden eyes stared each other down through the haze of heat that rose between them.

Yes, they had slept with each other.

No, it did not stop them from their competitive nature and seeking dominance.

That would never change.

Azula struck forward, blasting fire in his direction. Zuko rolled out of the way, swinging out with his left foot to send waves of flames towards her legs. Quickly, she back flipped out of the way momentarily grateful for the acrobatic lessons she had received from Ty lee. It didn't take long for her brother to get back on his feet, striking down with his right fist to send swirling twin sets of fire in her direction. Azula clenched her jaw, twirling her body with her arms out to create a shield of azure flames that surrounded her a second before his attack hit.

He's gotten a lot better since the last time we dueled… she thought grimly with brief irritation mixed with pride. I guess I'll have to stop taking it easy on him…

To Zuko's surprise, Azula ran towards him, quickly forming a fire like saw in her hands before sending it his way. He bent backwards as the blade of fire buzzed just a hair length past his face. The scar he had pulsated, painfully reminding him of the danger his element created. Straightening it up, he was greeted with a fire dagger a breath away from his throat and an arm snaking around his neck tightly.

This fight was over.

"Just like that…you're dead." Azula whispered in his ear seductively. He felt a shiver of fear and arousal shoot through him. Even when his life was in her hands, he still got turned on by it.

"If you submit to me like a good boy, I may let you off easy without another scar…" she smirked, bringing her lips to the back of his neck to kiss him. The touch electrified his nerves.

Zuko scoffed, knowing he was in no position to bargain "As if I would give in to you." Quick as he could, he elbowed her in the ribs while grabbing the flaming dagger, using his own bending to prevent damage. In her momentary pain, he twisted her arms towards her back, creating a flaming dagger of his own to hold against her throat. "How does it feel to know you were bested by your brother?"

Azula growled, hating herself from becoming distracted by the scent he gave off when she had kissed him. She felt his breath hot in her ear and his bare chest pressed up against her back. As much as she hated being defeated, she loved when he showed this darker side. "Now, now Zuzu…I never did say I was done playing with you yet." she purred, grinding her ass against his growing arousal. Turning her head, she kissed him on the lips, teasing him with the flick of her tongue. The cheap move proved useful as he let out a groan. She felt his grip loosen slightly and the heat from his flame die.

Predictable…

Her amber eyes flashed, as she ducked out of his grasp, swinging her right leg out to knock him to the ground. Not wasting time, she straddled his waist, grasping his hair to pull his head back, while she leaned down to hold the blue dagger to his neck. The fear flitting through his eyes made her feel powerful. She grinned deviously at his weak point "You don't have any self control do you?"

Zuko's eyes blazed with anger, submitting to her will without much choice. The look on his face made her smirk. "Don't be such a sore loser Zuzu, there's always next time…if you get lucky."

"You know that was a dirty trick Azula!" He snarled, hating how he had fallen so easy to that obvious ploy.

"Yes it was…but it's not my fault you fell for it now is it?" She could feel his pulsating erection pressing against her heated core. Snuffing out the flame dagger, she brushed her lips against his "Let me make it up to you." On instinct, she ground her hips, kissing him deeply.

Zuko complied, letting the frustration he felt seep away. Despite having lost to her again he couldn't help but find her infuriating superiority charming in its own way. His hands found her waist, holding her down so that the friction increased.

Azula moaned softly into his mouth, loving each time his cock rubbed against her clit. She broke contact to lay kisses down his neck, using her bending to make the sensation more pleasurable. She was rewarded with a groan deep within his throat. "Does this please you, Prince Zuko…?" She continued her actions, kissing down his chest, stomach, until she was greeted with his hardened erection underneath his pants. She pulled down the fabric to mid thigh. Holding his cock, she kissed the tip, taking in only the head, sucking it teasingly.

Zuko shivered, loving how she said his name in a way that made him growl with lust. He was overwhelmed with pleasure, amazed that she would actually be willing to go so far. He reached down with his right hand to hold her head as she attended to him "Yes it does…"

Azula took him in whole, bobbing her head up and down slowly. Pressing her tongue against his cock, she sucked at him, loving the sounds that he let out. She felt powerful in making him so weak and easily moldable to her will. The sensation of control over him made her wet, but she refused to please herself until he was satisfied.

She felt him buck his hips, knowing that he was getting close. Using her left hand, she grasped his dick as she continued, stroking him up and down. The saliva from her mouth made the friction greater. The double action caused his hips to jerk up aggressively, the grasp upon her head not releasing until he was relieved. Luckily for her, she was able to keep up in time with his thrusts.

"Damn Az…" He hissed, enjoying every subtle touch. He couldn't take it anymore. He needed her. Pulling his sister towards him, he locked his mouth with hers, slipping his tongue forcefully into her mouth. Flipping her over, he pulled down her pants so that he could brush his cock teasingly against her most sensitive area, loving how wet she was. She groaned in response, the sound music to his ears "You're amazing you know that?" He hissed, driving into her slowly, taking his time to feel every detail.

"Tell me something I don't know." Azula moaned, clawing his back with her razor sharp nails, feeling the tension in her body spread like fire.

Using his hands, he unraveled the cloth around her chest. Breaking their kiss, he licked and bit her neck all the way down to her breasts, kissing each nipple before taking one into his mouth. He sucked at her greedily, while his free hand groped her other breast, loving how she arched her back in response to his attention on her.

Azula couldn't stop herself from the noises that escaped her mouth, not caring one way or another who may come across them. If it were some servant they were easily disposed of…their father, however, would be a different story. It was a good thing he had a meeting today.

Zuko ground into her faster and deeper each time, causing her to whimper "Ohhh, Zuko don't stop!" His primal need must have taken over, as each time he entered her, she felt pain shoot through her but it turned her on even more. The friction against her G-spot drove her crazy with lust. She rolled her hips in time with his, increasing the pleasure between them.

Zuko brought his mouth back to hers, kissing her hard. He couldn't hold back anymore has he reached his climax. The pain from her claws made his pleasure intensify as the blood dripped down his back. His fists clenched on either side of her head, bursts of fire escaping his grasp. His sister screamed in ecstasy, her blue flames shooting out into the air just missing his face.

As she calmed down she gazed into his amber eyes that stared back at her with longing. Reaching up she cupped his face with her right hand, smiling "Are we even now?"

Zuko laughed, brushing the loosened strands from her ponytail behind her ear "Temporarily"

"Until the next time I kick your ass…?" She smirked, flipping him over to straddle his waist but this time there was no anger from him. All she could detect was love and that realization made her heart pound. Was this love real…? She let that thought go, fearing that it wasn't but not allowing it to consume her.

"How about tomorrow?" He gave her a wolfish grin, pulling her down to lock his lips with hers, never truly getting enough "…or perhaps tonight?"

"Sounds like a date." Azula responded with a smile, submitting herself to the one weakness she would never regret having.
